Create specialized symbol finder functions
...
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
This is useful for names that cannot be scoped, such as checking for EQUS.
Doing this instead of the third should improve performance somehwat, since
this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
and that the local part is not scoped. This is essentially the old function.
